Engine Coolant Mixture Ratio

WARNING: This page is about a different car, the 2019 Infiniti QX60. However, it is still accessible from the selected car via links, so may be relevant.

The engine cooling system is filled at the factory with a high-quality, year-round and extended life engine coolant. The high quality engine coolant contains the specific solutions effective for the anti-corrosion and the anti-freeze function. Therefore, additional cooling system additives are not necessary.

Coolant Mixture Ratios

For outside temperatures down to:		Anti-freeze coolant mixture ratio
deg. C	deg. F	Genuine NISSAN Engine Coolant or equivalent	Demineralized water or distilled water
- 15	5	30 %	70 %
- 35	- 30	50 %	50 %

CAUTION:

When adding or replacing coolant, be sure to use only a Genuine NISSAN Engine Coolant or equivalent in its quality with the proper mixture ratio. See the examples shown in the figure.

The use of other types of engine coolant may damage the engine cooling system.

When checking the engine coolant mixture ratio by the coolant hydrometer, use the chart below to correct your hydrometer reading (specific gravity) according to coolant temperature.

Unit: specific gravity

Mixed coolant specific gravity

Engine coolant mixture ratio	Coolant temperature deg.C (deg.F)
Engine coolant mixture ratio	15 (59)	25 (77)	35 (95)	45 (113)
30%	1.046 - 1.050	1.042 - 1.046	1.038 - 1.042	1.033 - 1.038
50%	1.076 - 1.080	1.070 - 1.076	1.065 - 1.071	1.059 - 1.065

WARNING: Do not remove the radiator cap when the engine is hot. Serious burns could occur from high pressure engine coolant escaping from the radiator. Wrap a thick cloth around the cap. Slowly turn it a quarter turn to allow built-up pressure to escape. Carefully remove the cap by turning it all the way.
